Definitions

  • the invention relates to a device for processing flat elements according to the preamble of claim 1.
  • suction belts for this purpose.
  • suction tapes are usually made of rubber or a similar material and have a large number of holes.
  • the transport device has at least two rollers over which this suction belt runs and below the upper section of the suction belt serving as a conveyor belt (i.e.
  • suction box which can be subjected to negative pressure, the top of which has a large number of openings, so that Negative pressure acting in the suction box, on the one hand, sucks the transport section onto the suction box, and on the other hand, sucks paper, which is on the surface of the transport section, onto this surface.
  • the present invention sets itself the task of further improving a generic device.
  • the conveyor belt also consists of a metal, but not of a fabric, but of an expanded metal.
  • Sheets made of expanded metal are manufactured industrially on a large scale.
  • a metal sheet is passed through rollers, with at least one of the rollers having a plurality of teeth which penetrate the metal sheet, thereby producing a regular hole pattern.
  • the holes are often diamond-shaped.
  • the expanded metal produced in this way can be calendered, which means that it is pressed between two rollers arranged in a gap.
  • Components made from expanded metal are used for a wide variety of applications, for example as filters or filter carriers or as cladding elements. What almost all of the uses mentioned so far have in common is that the expanded metal components are used purely statically.
  • endless belts made from expanded metal are excellently suited for the above-mentioned purpose from several aspects. They have a very good flatness, i.e. hardly any curvature in the transport area, are very durable and also show good scattering behavior with regard to the emerging laser light, which improves the quality of the products produced. Furthermore, these bands are very easy to clean.
  • the axes of the two deflection rollers of the conveyor belt usually lie in one plane. In order to prevent the conveyor belt from wandering sideways, it is preferred to keep the axis of a deflection roller pivotable within this plane, so that the angle between the axes of the deflection rollers can be changed.
  • An adjusting device for adjusting this axis is also preferably provided, which is further preferably part of a control loop. As a rule, it is sufficient and preferred to only adjust the non-driven axle.
  • the Figure 1 shows a schematic cross-sectional representation of a device for producing laser cuts in flat paper blanks such as greeting cards or the like.
  • the laser cutting device consists of four elements viz from a feed unit 40, a transport device 10, a laser 30 arranged above the transport device and a discharge unit 50.
  • the transport direction of the paper is the direction T and the device can work continuously, that is, the cutting contours are generated by the laser while the transport movement remains constant the transport device 10.
  • the Figure 2 shows a top view of the transport device 10 Figure 1 from direction R.
  • the feed unit 40 can be constructed conventionally, namely consisting of a table 42 with a smooth surface and a series of transport rollers 44, which feed the paper blanks to the transport device 10 by sliding over the table.
  • the transport rollers 44 can be turned slightly out of a 90 degree angle with respect to the transport direction T and thus press the paper blanks against a stop, so that a more precise positioning of the paper blanks is achieved.
  • the removal unit 50 can also be constructed conventionally and can, for example, consist of a connecting piece 52 and a conveyor belt 54. However, it would also be possible, for example, to provide a forklift or the like immediately after the transport device 10.
  • the essential elements of the transport device 10 are two rollers 12a, 12b, with at least one of the two rollers, here the rear roller 12b in the paper flow direction, being driven by a motor 13, the conveyor belt 25 and a plurality of axial fans 16, which are located below the upper Section (i.e. the respective transport section) 25a of the conveyor belt 25 are arranged.
  • a support 14 lying in the horizontal plane is used, which essentially extends from the front roller 12a to the rear roller 12b.
  • This carrier 14 has a large number of openings; the axial fans 16 are arranged at the positions of the openings, as shown in Figure 1 is only shown very schematically. In practice, the carrier 14 can also be made significantly thinner.
  • the axial fans 16 are preferably located relatively close to the underside of the upper section 25a of the conveyor belt.
  • the axes 12a' and 12b' of the rollers lie in one plane and the axis 12b' of the driven roller 12b preferably extends exactly perpendicular to the transport direction T.
  • the angle of the non-driven axis 12a' can be easily changed to the transport direction within the plane by a to prevent the conveyor belt 25 from “running away” to the side.
  • a few tenths of a degree around the neutral position in which the non-driven 12a' axis is parallel to the driven axis 12b'
  • a conveyor belt 5 according to the invention made of expanded metal would tend to do this without suitable countermeasures.
  • an adjusting element 80 which acts on a bearing 15 of the non-driven axle 12a '.
  • This actuating element can be designed, for example, as a linear motor or as a servo motor.
  • the adjusting element 80 can be designed in such a way that it allows a continuous adjustment of the angle of the axis or only a gradual adjustment of the same.
  • the actuating element is controlled by a controller 82, which in turn receives information from at least one belt position sensor.
  • a controller 82 which receives information from at least one belt position sensor.
  • there are two band position sensors namely a right band position sensor 84 and a left band position sensor 86.
  • These band position sensors can, for example, be designed as simple light barriers, which send a signal to the control when the band edge exceeds a predetermined position to the outside. If the controller is notified that the position has been exceeded to the right, it controls the actuating element so that the bearing 15 is moved in direction A, as a result of which the belt moves back to the center. If the control is notified that the position has been exceeded to the left, it controls the actuating element so that the bearing 15 is moved in the direction B.
  • a simple control loop for centering the conveyor belt is therefore formed.
  • a more complex (possibly single) belt position sensor could also be used.
  • centering at one end of the belt is sufficient.
  • the adjusting device can be designed so that it actively carries out both movements, or the bearing 15 can be biased in one direction (for example by means of a spring).
  • the conveyor belt 25 is designed as an expanded metal belt, for which the end faces of an expanded metal strip of suitable length and width are connected to one another, in particular by means of plasma or laser welding.
  • the expanded metal strip is preferably calendered.
  • the Figure 3 shows a small section of a suitable expanded metal
  • Figure 4 shows a section along plane AA in Figure 3 .
  • the openings in the expanded metal are similar diamonds with a first axis A1 and a second axis A2.
  • the axes are preferably of unequal length and the shorter axes (here the first axes A1) point in the transport direction T.
  • the conveyor belt between the rollers is very flat and still adapts to the radii of the rollers.
  • the length of the first axes A1 is between 1.5 mm and 4 mm and the length of the second axes is between 2.5 mm and 6 mm.
  • the free cross section of the conveyor belt is preferably between 50% and 70%.
  • the thickness of the expanded metal in the area of the "nodes", which are arranged between four openings, is slightly increased on one side, so that a substantially flat first surface 26a and a second surface 26b with slight elevations 26b 'results.
  • This structure results automatically in many calendered expanded metals.
  • the end faces of the expanded metal strip are connected to the conveyor belt in such a way that the first surface 26a points inwards and the second surface 26b points outwards, so that the transported sheets in the transport section 25a rest exclusively on these elevations 26b '. This has, among other things, advantages with regard to the back reflection of the laser beams.
  • the total thickness d g of the expanded metal is preferably between 0.2 mm and 0.5 mm.
  • the expanded metal is preferably made of stainless steel.
  • the transport device 10 can also have, for example, the following elements shown: input rollers 23, an output roller 20 and a lower cleaning brush 22 or a cleaning station. A preferred embodiment of such a cleaning station will be described later with reference to Figure 5 explained.
  • the cutting laser 30 is arranged above the transport device 10.
  • the device is operated continuously and at preferably a constant transport speed.
  • the paper blanks fed by the feed unit 40 are held in position by the axial fans 16, which suck air through the upper section 25a of the conveyor belt 25.
  • the air expelled by the axial fans 16 exits again through the lower section 25b of the conveyor belt and thus further contributes to cleaning the returning section of the conveyor belt 25.
  • the provision of axial fans has the further major advantages of a significantly reduced energy requirement and a significantly reduced noise generation (in conventional suction boxes, radial compressors are usually used as a vacuum generator).
  • the laser 30 cuts the paper blanks lying on the upper section of the conveyor belt, which leave the transport device 10 at the rear roller 12b and are removed via the discharge unit 50.
  • each side cheek has a slot extending in the transport direction, through which the axis of a roller extends, so that the distance between the two rollers 12a, 12b can be changed and thus the conveyor belt 25 can be tensioned .
  • the conveyor belt 25 can therefore also be used in finished, i.e. welded into an endless loop, assembled, whereby it is pushed laterally onto the rollers 12a, 12b; in this case, auxiliary units such as the input rollers 23, etc. may have to be removed.
  • the Figure 5 shows a preferred embodiment of a cleaning station 70, which can be arranged below the returning section 25 of the conveyor belt 25, for example at the location of the above-mentioned cleaning brush 22.
  • This cleaning station 70 has a cleaning roller 71 that can be driven about an axis 73 and an open-top container 76 for receiving cleaning liquid 77 (in the simplest case, water).
  • a stripping roller 78 is also provided, which is driven in opposite directions to the cleaning roller.
  • At least the outer jacket layer of the cleaning roller 71 is designed as a sponge (sponge jacket 74 - Figure 11) or in the form of a brush (brush jacket 75 - Figure 12).
  • the cleaning roller 71 is preferably driven in the same direction of rotation as the rollers 12a, 12b.
  • the cleaning roller 71 is positioned so that it presses from below against the returning section 25b of the conveyor belt 25 and its lower part is immersed in the cleaning liquid 77. As the cleaning roller rotates, new cleaning liquid 77 is constantly picked up and conveyed to the returning section 25b of the conveyor belt.
  • the level of moistening of the returning section can be adjusted by the stripping roller, which is arranged between the cleaning liquid and the conveyor belt in the direction of rotation of the cleaning roller.
  • the radial distance between the cleaning roller and the stripping roller 78 is preferably adjustable.
  • Moist cleaning (especially using the cleaning station just described) has several advantages. First of all, a good cleaning of the conveyor belt from combustion, ash and the like can be achieved. Furthermore, the humidification of the conveyor belt as such also has advantages: On the one hand, evaporative cooling occurs - additionally favored by the arrangement of the axial fans - that is, the conveyor belt, the upper section 25a of which is exposed to laser energy, is cooled. The humidification can also be adjusted in this way ensure that a certain amount of liquid still adheres to the conveyor belt on its upper section 25a. This adhering liquid improves the adhesion of burns, ash and the like so that they do not contaminate the back of the processed paper. The fabric structure of the metal conveyor belt strongly promotes the intentional adhesion of liquid.
  • the processing device described is also suitable for processing other flat elements such as cardboard, corrugated cardboard, textiles, leather or plastic films.
